* fix(dashboard): open the upgrade modal without navigating
Opening the upgrade modal set `?upgrade=true` via `goto`, which SvelteKit treats
as a navigation. On pages guarded by UnsavedChanges (the exercise editor, course
settings, certificates) that triggered the native "You have unsaved changes"
confirm before the modal could appear, and cancelling blocked it entirely.
The modal now lives in app state instead of the URL, so opening and closing it
never navigates. `?upgrade=true` is still honoured for billing emails and the
post-checkout return URL: it is consumed once on load and stripped from the
address bar with shallow routing.
Because checkout is an external redirect that unloads the page, editors can
register a handoff to persist in-progress work first. The exercise editor stashes
its draft, and the checkout return URL now points back at the page the user
upgraded from, so their questions are restored instead of lost.

* fix(dashboard): close question type select before opening upgrade modal
The select dropdown sits at z-250 while the upgrade dialog is z-200, so
opening the modal while the menu was still mounted left it covering the
dialog. Close the select first, wait for its close animation, then open
the upgrade modal.

* fix(dashboard): close question-type select before opening upgrade modal
The premium-type button left the select open, and its z-menu-elevated
content sat in front of the upgrade dialog. Close the select first and
wait for the close animation before opening the modal.
